How is there a market outlook for battery repair?

At present, the application of batteries has penetrated into all aspects of people's production and life, especially after the global oil crisis has erupted multiple times, people in the diversified development and high efficiency of future energy applications, the battery storage has been compared to improving water level storage. Methods such as electrolyte hydrogen storage and storage of hydrogen storage have unique characteristics of high energy storage efficiency, which can easily form a power application system of different voltage and capacity. At the same time Work power supply and emergency spare power supply for various mobile devices. The many excellent characteristics of this product are in the future social development, and other electric energy storage products and methods are difficult to replace. It is one of the most promising power applications in the future.
However, due to people's understanding of some of the most basic problems in batteries, there are still many reasons that have not fully understood. It makes it difficult to maintain the battery during use, and it is difficult to obtain effective guarantee for safety. The life span during use is elusive, resulting in the cost of batteries too high, which affects some products that need to be used in large -scale batteries today, such as electric vehicles, such as electric vehicles, such as electric vehicles. The real high efficiency, low cost, high -reliability industrialization development process of renewable energy power generation systems and various reserve emergency power supply.
This of these problems, the capacity of the battery — A._H, is one of the most critical issues. This article focuses on the important parameters of how to further study, understand, grasp and use the battery capacity.
1 The problem of definition of the battery capacity
The battery capacity is the value of the power size after the battery is sufficient. The unit is An Shi (A · H). In the formula: C is the time of the battery capacity (a · h);
i is the battery discharge current (A);
T is the battery discharge time (H).
(1) describes the size of the power capacity of battery storage. If further inquiries, many classic battery works and textbooks have pointed out that in the case of limited battery capacity, the size of the measurement load in the formula (1) and the decarning voltage of the measurement during measurement will affect the capacity of the capacity. Value (a · h) measurement size. Therefore, the capacity is not a single value. Its size, compliance with the conditions and environment of measurement and use. Under the strict requirements, the capacity value obtained by the experiment (1) can be easily used to compare the battery storage power capacity. However, abuse under the strict stipulated conditions is the root cause of many problems in the daily use of batteries that cannot be made in the daily use of batteries.
2 The need for measurement of battery capacity and difficulty
The battery capacity under specific experimental conditions is an important parameter for evaluating the quality of battery performance, and it is also the basis for the working time of the battery to work under the fixed -value load; it is also the condition for this condition The so -called charging standards after a completely discharged battery. The reason why it emphasizes completely discharge is that people want to have a unified starting point for charging after each discharge experiment to facilitate the determination of the maximum charging current of the battery charging process, and the safety of the battery charging; it is easier for the charger Options, unity and simplification of control and charging process control. In order to charge the battery in general use, it can also have the safety parts of the laboratory conditions. People have always hoped to find a way to quickly measure the battery capacity under daily application conditions. The main purpose is the following two aspects:
(1) It is used to determine the termination point of the battery discharge process under different use environments and conditions in time, that is, the unified charging starting point of the same battery after discharge;
((( 2) It is used to determine the full -scale battery in different environments in order to timely turn off the charging current of the battery in time, and avoid the out of control damage caused by over -charging the charging battery.
. For example, the measurement method of battery voltage changes widely adopted in real applications, the internal resistance of battery internal resistance, and the SOC measurement method now proposed are specific practices that people want to realize this idea. The voltage and internal resistance of the battery does not have an inevitable linear relationship with the battery capacity. Only the integral of the battery discharge current on the timeline is the real capacity of the battery. The relationship between battery voltage, internal resistance, and battery capacity, even if there is a little imagination, is difficult for people to grasp and use it accurately due to the objective existence of non -linear characteristics. As for the SOC measurement method: Generally speaking, it is the battery -storage load state judgment method. The original equation derived is:

: SOC is the percentage of the real -time capacity of the battery and the rated capacity of the factory:
CR is the available capacity measured (A.H) measured on the load;
C is the rated capacity (A · H) given by the battery.
Is whether the capacity value of the capacity on the battery load can accurately represent the decrease value of the capacity in the battery. As far as C as the base C in the SOC measurement method, people's recognized battery capacity equations have indicated that it is not a single value, and its size must be complied with the conditions for measurement and use. It is obviously the role of some people as a subjective factors as a subjective factors. Therefore, it is impossible to use the measurement and SOC measurement method of a single voltage change value and internal resistance change value of the battery. Real -time actual capacity in daily use. Therefore, the charging after the battery is discharged, it is difficult to fall at the same starting point. In the same reason, it is difficult to accurately judge the state of battery charging. This is the fundamental reason why the charging process in the use of batteries is often caused by problems.
If the complex non -linear relationship between the battery, the internal resistance, and the capacity of the capacity, some people are difficult to understand and accept it for a while, so use more intuitive and simpler logical reasoning therapy, and use the end voltage change value of the battery. To judge the lack of scientific basis for the internal resistance change value, it is believed that people will not be difficult to understand: people recognized by people's battery capacity verification equations have been listed earlier. The points of time factor, that is, if someone is hard to use the measurement of voltage or internal resistance outside the capacity equation to determine the capacity of the battery, it is obviously a subjective method of wishful thinking.
3 Battery capacity The cause of uncertainty during use
Generally speaking, the battery is different from the laboratory experiments in the actual use of the user, and there are strict regulations for environmental temperature and load. In a large changing environment, the unstable batteries of general chemical products are not exceptions, which will inevitably lead to a battery parameter, including a certain range of uncertain changes in the capacity parameters.
The capacity of the battery before the battery is not a single value. The size is based on the measurement conditions. Even in the laboratory, the same charging battery is discharged with different currents such as 2C and 0.5C. The capacity is very large. Different, this is already common sense. When the user uses a battery, the actual load is a large -scale change of load, such as great uncertainty on electric transportation products.
It batteries, just like driving cars to use fuel, it is impossible to achieve the same road conditions of the car every day. The distance, speed, loading, etc. are the same. The amount of fuel consumed every day is not the same. The use of batteries is extremely similar to this, because the battery in use, the uncertain factors encountered every day in use, are not only unpredictable before use. It is also impossible to know during use. Therefore, it is impossible to accurately know how much the capacity of the battery is used.
is not only that, it is also related to the following problems: the battery energy storage system, which is different from the way of storage of energy and substances in fuel vehicles. The losses when the fuel vehicle takes out the fuel from the fuel from the fuel to the engine burning room is extremely small and can be ignored. Therefore, the remaining oil in the fuel tank is easy to know. The battery is not the same. While providing a current output to the working load, there is an energy loss that cannot be ignored in the battery internal resistance and contact resistance. Moreover, the size of this loss is proportional to the size and time of the energy output of the battery. And diverge to the surrounding space in a thermal energy manner. Under general conditions, this divergent loss is difficult to measure accurately.
Therefore, how much the capacity of the battery has a lot of uncertainty after each use of the battery. This objective facts just answered the CR value measured on the load in the previous SOC measurement method, which cannot be used to represent the actual capacity of the actual capacity of the battery in daily use. This also lacks the SOC measurement method from another side. The scientific basis made a more objective and reasonable answer.
The objective speaking, there is one thing that is worthy of attention. The energy storage of batteries is essentially different from the general energy storage method of the car. Once the fuel tank of the steam port has become a product, unless there is an accident, the volume of the storage of fuel substances generally does not change with the environment. The battery has different batteries. Although the appearance of the product does not seem to have changed much with the environment after becoming a product, the size and capabilities of the storage power of the storage power changes with the external environment. This is also one of the complex issues that are difficult to control the battery energy storage system.
4 The loss of charging standards
It the core issues discussed in this article below. Since the invention is used, the battery is carried out, and the capacity marked on the shell is saved. One of the most important parameters for choosing is the standard of measuring, over -charging, and charging with owed charging in the future in the future.
The as a standard, the conditions that must be available (a · h) must have: no matter how the battery uses the conditions, the environment, and time changes, at least the battery should be safe during the life period of the design and use (A. · A. h) The value should be stable. Because of the size of the capacity, in addition to the necessary conditions for people to provide sufficient energy to the workload in use, it is also the so -called so -called battery to ensure the safety and reasonable use of the battery. Essence Once the charger is selected, the charging process after the battery will be discharged in the future, and the current, voltage, time, and procedures determined by the factory marked capacity (A · H) can be charged to recover the capacity of the battery. Whether the battery has the principle and characteristics of the unchanged value (A.H) value in people's daily use. From the capacity equation to the difficulty of measurement and the occurrence of uncertain factors, it has been discussed a lot. In order to further explain the problem, it is necessary to repeat the focus on the focus. The battery in the user's hands, due to the changes in the environment, the length of the use time, the different reasons of the discharge current, the remaining value of the battery before charging, people cannot grasp it accurately. Take a step back, even if the user uses each time, it can accurately measure the capacity value of the battery on the load. Due to the drift and instability of the labeling capacity of the battery in different environments, the internal resistance of the battery during use, etc. The heat loss cannot be accurately learned. The capacity safety value (A · H) is different from the battery use process, and there are different declines. It is impossible for people to accurately grasp the real actual capacity value before charging the battery. What's more important is that the battery capacity is fast and real -time measurement method. So far, people do not know where it is, and the stable and unchanged capacity value standard is just one of the imagination. And leverage, it does not exist objectively. The surplus capacity before charging the actual use of the battery is 5 % to 50 %, or even 80 % of the different situations such as the factory. Due to the existence of many uncertain factors in the use of batteries, it should often appear and inevitably appear and inevitably occur. Essence From this point of view, the actual capacity of the battery after each use of the battery (A · H) has a big difference from the factory labeling value used as a standard. In the past, the battery accumulation of the charging standard was marked with the capacity of the capacity (A.H). At this time, the rationality and science no longer existed. As a result, the loss of battery charging standards is actually lost. This loss has also made the scientificity and rationality of the charger selected by the battery's factory marking the capacity value. Therefore, the battery in actual use often occurs with heat out of control. The problem of charging and charging is really a cause.
It if people still have questions about the above views and discussions, let's give you a common example for everyone to investigate, observe, and think. In the current rapid development of light electric vehicle in my country, the commonly used plastic shell valve control battery packs, regardless of whether the charger is equipped with a constant or constant voltage method, or a popular multi -segment charger now, uses one to use one. In the year or even a few months, a large number of batteries appeared to be scrapped. In the final analysis, most of them were caused by the loss of charging standards in the use of batteries.
Recently, several world -renowned computer companies recall a large number of laptop computers produced by Japan's Sony Company, and the reason for the same similarities is that the heat is out of control. The long -term existence of heat out of control in different batteries is an objective fact that cannot be ignored and avoided. At the same time, it is also the most sad -minded and most difficult and difficult problem in the development of battery technology today. We believe that the main reason for the problem of thermal loss of control is undoubtedly the result of the battery lost the charging standard under the guidance of traditional charging theory.
5 Conclusion
The basic common sense tells us that the correct argument of any scientific theory should have a stable objective standard. And can accept experiments, use and time verification for a long time. The value value of the factory labeling of the battery is clearly an unstable parameter with changes in the use conditions, environment and time. The long -term standard for charging batteries with such a parameter is obviously a wrong practice that violates scientific common sense.
The loss of batteries is self -evident. It inevitably affects the correct use and service life of the battery, and also affects the research, design and manufacturing ideas of batteries. The traditional set of traditional battery charging theories, which is widely used, has a large difference in the complexity characteristics of the non -linear system that objectively exists in the battery. People are obviously limited by traditional epistemology and methods, which has led to the long -term use of the batteries that have been used in the use of batteries to be unsolvable. Only by jumping out of the constraints of the traditional charging theory, attaching importance to the inherent rules of the battery, finding out the cause of the problem, and taking appropriate measures for the reasons, can the problems occur in the battery use and realize the real solution.

The battery activator is generally involved as soon as possible. You can set up multiple cycle cycles to recycling the minimum capacity battery to stimulate the active substance of the battery plate failure to activate the battery to activate the battery. Make the actual service life of the battery closer to the service life of the battery.
Note that no backward batteries can be activated. What the activist can adapt is only part of the backward reasons in the chemical failure. As for the physical fault activity instrument Short -circuit and so on.
